` LTO ALL WHOM IT MAY CONCERN;

Be it known' that I, F. B. Mouse, of 'New Haven, Ain the county of New Hiive'n'g'and State of Connecticut, have invented a newIulprovenient in Stump-'Joint for Gnrrioges; und I de herehy deelorqthe following, ryhen' taken in connection with the accompanying' drawings, and the letters of reference marked thereon, to be a.' full, 'i clear, and cxactdescription of .the same, und which said drawings constitute-partof-'this,speciiicntiomand represent, ifi- Figure 1, n side view ofthe joint closed, Figure Zan end view ofthe sume, l

.Figure 3 a centralse'cti 'n ofthe joint closed, und inl l Figure` a like section, the joi'nt ppen. i t l f This invention relates to en improvemen-t' in the article of manufacture commonly celled stump-joint for cnrieges, tha.t is to say, the` joint which unites the parts of, the braces which-support the topot tharrige, and by menus of which the topmay bedroppedat pleasure. The object of the invention isto simplify the construction, and produce a s'tronglanddnrable article-ata comparatively' 'small cost. -To this end the invern-- tion consists in forming recess in the meeting ends of the joint, und placing therein` n. linker hinge-plete,` of a form correspondingto .the recess in the joint, s that, when open or elosedythe plate-and parte of the; joint come to a` firm bearing, so us topreveut the joint from becoming f sheeklyby,c0ustn use,

' lIn order to the clear understanding of my invention, 'I will -fully` describe the sume' hs illustrated in' the' accompanying drnwings. i',

.Aie-the one part, B the other, usually 'formed from square metal, of the size proportionate to the style of .carriage for which it is'intended. In the end of each of the parts A and '3,1 form e recess, denoted in figs;

v2 and 3, and in order to do this bymnchineryg I form the recess in ench of a quarter circle, s othnt umillingtool, of the proper diameter, will cnt the recess of the proper form, the centre' of the circulo.;` cut being at the' inner meeting nngle'of the tiro parts; than, at n poin`t,a, in euch,'eq'uidistant `frein Vtheinner edge and oud, I `borethroughi'or tho pivot. C is the connecting. hinge-plate, formed so that rivets d will pss's therethrough, -and the said plete of such forniv thntwhen the tn 'o parts are closed, as in iig. 8, theedge of the plete O will. hear against the slot in both parts,- as` at'fig. 3,-faud thus prevent any moilement or end thrust of the two pints, end also that when the tivo pz1 rts are open,- asiniig. 4, the` opposite side of the plete C will strike. 'the slot-in the two -pnrts et Il, (ses fig. 4,) and in like manner support theY two-parts in n xed rigid position.

The inner angle of the two ports should he rounded, tilting the pivot as n centr'e, s o that the pn'rts Will open one upon the other. This portion' of the parte A andfheing cut away, affords roomfor the shaft o f the cutter, which forms -the s lot in the end of the parts. t

The pint-c C is cut from a plate of suitable rnetnl by n die of the proper form,'and punched, so that the expense of fitting the plete is vgrytriiiing. v

l Upon the outer and opposif'e'sides of thetwo pnrtsI piace round plates or buttons D`, through which pivote d pss Vandere riveted, so as.to secure the buttons in their pince, therebyforming s support to the pa-ts, as

well ss 'nn ornnmentnt the joint. f

Having thus fully described my invention,

Patent', s-f l A 1. A stump-joint, consisting of the two parte A end B, joined by theplnte C und pivots d d, when the said plate C-is errnngodnml fitted into theparts Aond B, so as to operate in the manner specified.

what I cla-iin` as n ew and useful, anfd'desiro to secureby Letters ,2. In combinntion vwith u stump-joint, I claim the buttons `or plates D D, arranged upoln; opposite sides of thejoints; suhtnntinll'jl in themnnnerherein set'fqrth. l i I l, l i F. 'B' MORSE: i Witnesses:
